What should be the address and port in the DOCKER_HOST_PATH to communicate with the Docker daemon via Plaintext in Bottlerocket?

When using dockershim.sock in Bottlerocket, I want to use it without TLS. What should be the address and port in the DOCKER_HOST_PATH to communicate with the Docker daemon via Plaintext in Bottlerocket?

For reference, I'm running Jenkins' Docker in Docker model on Bottlerocket, with the host volume mounted as follows

volumes:
- type: HostPath
hostPath: /var/run/dockershim.sock
mountPath: /var/run/docker.sock

I used port 2375 and got the following error

Cannot connect to the Docker daemon at tcp://localhost:2375. Is the docker daemon running?

This is a shot in the dark, but do you get the same behavior if you mount to /run instead of /var/run? (Just want to rule out selinux.)

Also is this the ecs variant or k8s? Docker is only available in our ecs variants, whereas k8s variants use containerd.
